Bausch + Lomb - contact lenses for everyone
The leading position in the manufacture of vision correction is taken by Bausch + Lomb, one of the oldest operating companies in the United States. The sales of contact lenses bring her 31% of income. The most demanded contact lenses Optima, Bausch + Lomb Pure Vision, Soflens and MultiVision.
The history of
The company was founded by a German native John Bausch in 1853. He opened the optics, and later a friend Henry Lomb became his full partner.
The enterprise manufactured rims of rubber, binoculars, microscopes, other precise optics, including for military needs. This was facilitated by the cooperation with Carl Zeiss, the leader in the production of optical instruments. The company was among the first manufacturers of sunglasses, produced for the US Air Force( Ray-Ban).
In 1966, the company obtained a license to manufacture and trade contact lenses from water absorbing hydrophilic material. In 1971, 100 thousand pairs of Softlens lenses were sold.
In 1987, the FDA approved the sale of lenses with a Teflon-like coating, preventing the deposition of protein and making the lens more convenient.
Soflens 66 lenses, which became widely popular, were released in the early 90's. And in 1993, thanks to the acquisition of Laboratories Conoptica and Polymer Technology, the first oxygen-permeable means of vision correction appeared. At the end of the last century, a technological breakthrough occurred - Bausch + Lomb Pure Vision contact lenses were designed for permanent wearing.
Production facilities and trading enterprises of the company, whose staff exceeds 10 thousand employees, are located in 25 countries. The headquarters is based in Rochester.
The main characteristics of contact lenses
Lenses can be soft and rigid. Hard lenses are durable, durable, smaller, better "breathe", so they wear longer. However, they are less comfortable, they can change the shape of the cornea, reducing the visual acuity in the glasses.
The main materials used in the manufacture of soft lenses are hydrogel and silicone hydrogel. Hydrogel passes oxygen worse, so the maximum period of safe wearing of such lenses does not exceed 15 hours. Its excess is fraught with hypoxia of the cornea of the eye.
According to the frequency of replacement contact vision correction devices are divided into one-day, weekly, monthly, quarterly and annual. One-day most hygienic - care is not required and discarded after use.
The wearing mode can be daily( up to 15 hours), prolonged( up to 7 days), flexible( up to 2 days), continuous( up to 30 days) and night( to correct the shape of the cornea during sleep).
Design can be spherical, toric and multifocal. Myopia and hypermetropia are corrected by spherical, astigmatism - toric, age-long-sightedness - by multifocal lenses.
The presence of a UV-filter will protect the eye from ultraviolet radiation.
Color lenses imitate the iris and allow you to change its color.
Company products
The company produces products for vision correction for hyperopia, myopia, astigmatism, presbyopia, cataract, keratoconus and other eye diseases.
The optimal choice for people who prefer lenses of planned replacement, are contact lenses Bausch + Lomb Optima FW.Choosing a permanent wearing or high-quality vision is suitable lenses PureVision and PureVision2.Suffering astigmatism will help another product Bausch + Lomb - contact lenses Sof Lens Toric. Age-related farsightedness can help fix SofLens Multi-Focal. Young people like the colorful contact lenses Bausch + Lomb Sof Lens Natural Colors.
Optimal
Contact lenses Bausch + Lomb Optima FW from hydrogel are designed for wearing in the day no longer than three months. Oxygen permeability is 24,3 DK / t. The liquid content is 38.6%.
Characteristic differences:
- method of production - centrifugal casting from "polymacon", non-ionic strong material;
- smoothness of the surface, reducing the level of protein deposits;
- optimum mobility and alignment;
- Convenience of handling, provided by light pale blue tinting.
PureVision
Produced from silicone hydrogel "balafilkon A".To wear it is necessary constantly or in the day no more than one month. The water content is 36%.The permeability is 112.0 DK / t. The design is aspherical. Tint is light blue.
Advantages:
- front aspheric optics improves the quality of vision in poor light conditions and reduces spherical aberrations;
- using a combination of a hydrophilic hydrogel and a high oxygen permeability silicone( AerGel technology) opens up natural oxygen access to the eye cornea and constantly moistens the lenses;
- surface of contact lenses is processed by plasma, which gives it an ideal smoothness and high wettability;
- thickened middle and thin rounded edges provide excellent mobility and constant movement of tear fluid under the contact lens.
PureVision2
New Bausch + Lomb - contact lenses Pure Vision 2 - aspherical light blue lenses made of silicone hydrogel "balafilkon A" are designed for permanent wearing or wearing in the day no longer than a month. The liquid content is 36%.The permeability is 130.0 DK / t.
These lenses are designed for PC users, motorists and anyone who needs clear vision in conditions of artificial or insufficient daylight. Their differences:
- Special optics of high definition reduces spherical aberration, glare and halos, which makes it possible to see clearly, without rainbow circles and glare, even in poor light conditions.
- A small thickness that makes the lenses almost imperceptible.
- Smooth surface and rounded edges for comfortable wearing.
- High oxygen permeability of silicone hydrogel, which reduces the likelihood of hypoxia and provides the eye with sufficient oxygen.
Colored
Colored contact lenses Bausch + Lomb Sof Lens Natural Colors from the hydrogel "polymakon" are designed to be worn during the day with a replacement every 3 months. The liquid content is 38.6%.The oxygen permeability is 14.0 DK / t.
- Features the following features:
- Nine shades: platinum( gray), aquamarine( turquoise green), indigo( purple), jade( light green), Pacific Ocean( blue), "Amazon "(green)," topaz "(blue)," emerald "(dark green)," India "(nutty).
- Special application of color and limbal ring make eye color close to natural.
- Smooth surface, resistant to protein deposits.
- Resistance to dehydration.
- Optimal mobility and alignment.
Sof Lens Toric
Another Bausch + Lomb product, Sof Lens Toric contact lenses, is a toric lens made of the "alphaphylcon A" hydrogel. Wearing in the afternoon and monthly replacement. The permeability is 16.0 DK / t. The liquid content is 66%.Designed for people suffering from astigmatism.
The advantages are as follows:
- The unique double curvature of the lens with a flatter surface in the center and steep edges allows for the best possible centering and clear vision.
- Good axis stabilization is achieved by thickening from the center to the edge of the contact lens.
- The radius of the outer and inner parts of the lens is chosen to reduce the thickness and optimal stability of the lens.
- The reduction in weight, as well as the rounded edge of the lens, results in a comfortable wearing and optimal lens mobility.
Sof Lens Multi-Focal
The next Bausch + Lomb product - Sof Lens Multi-Focal contact lenses, light-blue multifocal lenses from the hydro-gel "polymakon B" - will help suffering from age-related farsightedness. It is recommended to wear the day and a monthly replacement. The liquid content is 38.6%.Oxygen permeability is DK / t.
Advantages:
- Balanced mass distribution, which improves the centering and operation of aspheric optics.
- A wide transition between the near and far optical range ensures clearness of vision regardless of distance.
- The transition zone smoothly changes the focus between the near and far, keeping the clarity at intermediate distances.
- The rounded edges of the contact lens gently slide over the eye cornea.
Only a small part of the company's products are listed here, however you can be sure that what contact lenses are not purchased, they will always be of high quality - the legendary American quality of one of the oldest US companies.
